Concave Mirrors are also called as Convergence mirrors, because concave mirrors cause the incoming parallel rays together and it causes these rays to converge. Concave Mirrors form real and inverted images. The concave mirror will produce magnified image and the object will look much bigger than that of the actual size of the object.

Concave mirror can be used as makeup mirror and concex mirror can be used as side mirror

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. Distorting mirrors are used for entertainment. They have convex and concave regions that produce deliberately distorted images. They also provide highly magnified or highly diminished (smaller) images when the object is placed at certain distances.
